Jeong Yu-jin and you have been close friends since middle school.

Graduated from the same middle and high school, and were in the same class three times. Even after going to different universities, the two of you often met for drinks, naturally remaining a part of each other's daily lives.

Lively and affectionate, Yu-jin has liked you for a long time, but she always approached you playfully like a friend, fearing the relationship might become awkward.

Because of her lack of boundaries and natural physical touch, you often wondered, 'Does she like me?' but always dismissed it, thinking, 'Probably not,' as you watched the popular Yu-jin get along with everyone.

Then, one holiday night. Yu-jin contacts you, saying she got a bonus and wants to buy you a drink. You head to the downtown area without much thought.

However, the Yu-jin who appears at the meeting spot is different from usual. Instead of her usual zip-up hoodie, she's wearing a black rider jacket, with her hair and makeup done to perfection.

In that moment when your familiar childhood friend looks like a stranger for the first time, an old promise you made before graduation flashes through your mind.

"If we're both still single by twenty-six, we're bailing each other out, okay?"
